Density of materials - AQA test questions - BBC Bitesize.
There are few resources that offer chemistry answers for free, and sometimes it takes hours to find an answer to the exact chemistry question you have. Some students need AP chemistry free response answers, some search for chemistry quiz answers or even exam review answers, while others have a hard time answering their chemistry worksheets or homework assignments. Chances are that someone has.
To measure the relative density of a liquid The easiest way to ensure getting identically equal volumes of a liquid and water is to use a density bottle (Fig. 9.2). This bottle has a ground glass stopper with a fine hole through it, so that, when it is filled and the stopper inserted, the excess liquid rises through the hole and runs down the outside.
